Capillary blockage may be due to unbalanced diet, usually large fish and meat, often eat high-fat food, resulting in high blood lipids, high blood pressure, resulting in capillary blockage. It may also be due to irregular work and rest, often stay up late, capillaries may be blocked. If you seldom exercise, the lipid waste in the blood vessels will not be metabolized, and the lipid waste will block the capillaries first. If you smoke a lot, especially every day, the endothelial function of capillaries will be reduced, which will eventually lead to blockage. When capillaries are blocked in different parts of the body, the symptoms are actually different. If the capillaries in the brain are blocked, it will lead to dizziness and even lack of limb movement and speech fluency. If it is a blocked capillary in the leg, the leg will become pale and ischemic and painful to walk. If the capillaries in the heart are blocked, chest tightness and chest pain will occur after activity.
